Question
which is NOT true about ozone and it's alternatives?
A. hydrofluorocarbons cannot contain chlorine
B. hydrofluorocarbons contain hydrogen, which enable them to be more easily removed from the air before they make it to the stratosphere
C. brominated carbon compounds can be more hazardous to the ozone layer, but are present in lower concentration
D. chlorine-carbon bonds are more easily broken than carbon-fluorine bonds
E. iodine-carbon bonds are the most easily broken of the halogen-carbon bonds
Explanation / Answer
The 5th statement i.e iodine-carbon bonds are the most easily broken of the halogen-carbon bonds is true but not valuabe in case of ozone depletion. Ozone depletion is mainly affected by chlorine and bromine. Hydrofluorocarbon is prepared in such a way that it does not contain chlorine. So HFC keeps the ozone layer safe.
